This is the first course in a Coursera Specialization track involving Web Application Architectures. This course will give you the basic background, terminology and fundamental concepts that you need to understand in order to build modern full stack web applications. A full stack web developer is familiar with each "layer" of the software technologies involved in a web application, including data modeling and database technologies, the web server environment and middleware components, network protocols, the user interface and basic visual design and user interaction concepts.
In this course we will learn by doing. We will start by learning the major components of web application architectures, along with the fundamental design patterns and philosophies that are used to organize them. You will build and continually refine a fully functional full-stack web application as we progress through the modules in this course. Along the way you will be exposed to agile software development practices, numerous tools that software engineers are expected to know how to use, and a modern web application development framework.
This course is also available in Spanish. To join the Spanish version, visit this page: https://www.coursera.org/learn/apliweb.

Module #3 - Managing Data

A successful web application provides information t
o users that is (1) useful, and also (2)
easy to access and understand. This information is
often collected from users, as well as
from other information sources, and must be stored
in a manner that allows it to be
manipulated by the web application. The typical app
roach is to store this data in a
relational database. In this module you will learn
some basic concepts associated with
modeling the data in a web application, including h
ow to specify the relationships between
various data entities. We will also investigate ho
w to hook a web application up to a back-
end data store, along with good design techniques t
hat will make it easier to use the data in
your web applications by maintaining consistency th
roughout the entire web stack.
